How to Get nRF52840 & nRF52833 Module Zephyr Project Started

Zephyr is hosted by The Linux Foundation, which is an open source to build a small, scalable, real-time operating system (RTOS) across multiple architectures. Zephyr Project’s is aiming to provide a collaborative effort between technologies to reduce the cost and accelerate time to market for Internet of Things (IoT) industry.

Nordic, the leading wireless solution provider across Bluetooth, WiFI, LTE, NB-IOT, provides documentation for developers which are interested in starting Zephyr projects. Nordic Zephyr Project Support Page.

Raytac, a Taiwan base professional module maker built up various form factor modules based on Nordic solution, has listed both nRF52833 / MDBT50Q-DB-33 and nRF52840 / MDBT50Q-DB-40 module demo boards in Zephyr support boards data base. Believed these completed and comprehensive support boards reference design can provide all developers a break through path toward success.

c. Locate all the necessary kits for programming in PC (Check Software/Application list)



3. To recognize your nRFConnect SDK version case by case

Intro: The preparation of nRF Connect SDK Vx.x.x(NCS SDK version, ) and Nordic Example code will help you get through the program code building and trace debug in VS Code IDE or Segger Embedded Studio IDE. Here’s the brief way to recognize your nRFConnect SDK version which suits your project development.


  Activated your “nRF Connect for Desktop”  >> “Toolchain Manager” >> “Open” >> “Install”

(**Note: The development nRF Connect SDK(NCS) provides with free VS Code IDE and Segger Embedded Studio IDE as compiling system)


To recognize your project is with or without Audio inquiry and download the “nRF Connect SDK(NCS)” by the following classification.

A.) Project with Non-Audio case

Option1. Go with NCS V1.9.1 (Included) and previous version.

There’re either “Open VS Code” or “Open Segger Embedded Studio” IDE options could be selected for program coding.

Option2. Go with NCS V2.0.0(included) and the later.

 There’s simply “Open VS Code” IDE that could be run for program coding.

B.) Project with “Audio” inquiry

You would only have option of NCS V2.0.0(included) and the later version working in “Open VS Code” IDE.


 Please make sure the nRFConnect SDK is installed at same base directory with compiling system  (the root of Open VS Code)

(This is using D:\ncs-work base as example.)    

If the base is not directing to the same, do “Select directory’” to re-direct the route.
